application Ms, 1e, 1940, sei-lam. 335,507 4 claims. (ci. 'zz-11s) My invention relates to ceiling structures adapted to support acoustical tiles, and its main object is to prvide a simple and emcient metal-l lic suspension for the til/ es which embraces inverted T-shaped metallic suspension members whose anges enter grooves in the edges of the tiles, and metallic clips which are hung from hangers carried by the usual oor construction and provide extendedand resilient saddles to engage flanges of the suspension members. A further object is to provide a clip of this character which is inexpensive to manufacture from metal blanks and provides a suspension head and one-piece bodyl which is bent at its lower portion into opposite flanges to support and interlock with the anges of the suspension members. Other objects will be apparent from the disclosure.

" In the accompanying drawing which illustrates my invention, Fig. 1 is a top plan view of a ceiling structure embodying sound-absorbing tiles supported by my suspension devices, parts being broken away for convenience of illustration; Fig. 2 is a detail sectional view taken in the plane of line 2-2 in Fig. 1, the parts being shown on an enlarged scale; Fig. 3 is a similar view in the plane of the line 3--3 in Fig. 1; Fig. 4 is a perspective view of part of one of the metallic T suspension members; Fig. 5

is a similar View of part of one of the metallic transverse T suspension members; Fig. 6 is a similar view of one of the metallic clips; Figs. 7 and 8 are views showing a modied form of constructionof the clips and their supporting members.

In the drawing, the reference numeral I in-f dicates metallic channel members whichare carried by suitable supporting members provided in the ceiling construction, such as parallel metallic runners spaced about four feet apart on centers and hung to presenta. level under surface. here there is a plastered ceiling construction, the channel members may be attached to it by suitable toggle bolts and brought to a level surface. The channels are formed in cross-section with opposite depending webs Il and inturned anges I2 forming supporting runways for the suspension clips.

The clips are made from at blanks of galvanized metal, having T-shaped heads I3 adapted to enter the channels in the members Ill and depending skirts .I4 whose lower portions are bent and rebent to form opposite flanges I and I6. The latter i'lange extends on vboth sides of flanges I1 of the associated tile suspension members Il. The latter are inverted metallic T members extending below and transverse to the channel members I0. The flanges I5 and I6 of the clips are elongated in the line of the flanges I1 of the suspension members I8 to aiord extended support for the latter, and the spaces between the ilanges I5 and I6 into which the flanges I1 of the members I8 enter is reduced so that the flanges I1 are tightly gripped by the flanges I5 and I6. This construction affords an elongated and wide seat for the suspension members, and the resiliency of the flanges I6 causes the clips to tightly grip the flanges I1 and interlock the parts together. The flanges I1 of the suspension members engage grooves in the edges of the tiles I9, which are of predetermined length and breadth, their latter dimension being appropriate to flll the spaces between the median lines of the parallel supporting members I0.

Similar T-shaped suspension members 20 shown in Fig. 5 are installed transversely of the members I8 between the ends of adjacent tiles in the rows, with their lateral flanges 2l and 22 in the grooves in the tile ends. 'I'he flanges 2| and 22 are cut-back attheir ends so that they aline with the flanges I1 of the members I 8 Yto make smooth joints in the line of the grooves in the tiles. The projecting ends oi the suspension members 20 rest on the flanges I1l so that the entire tile-suspending structure is carried by the clips I3.

In Figs. 7 and 8 I show a modified construction f of the clips used when their supporting members are in the form of I-beams 23 having out-turned webs 24. In this embodiment the clips are cutaway in their upper portion to provide clearance with their supporting beams, and are formed with opposite inwardly directed arms 25 resting on the webs 24 and with anges 26 and 21 corresponding to the flanges I 5 and I 6.

When the clips are used adjacent to a wall, their lower flanges I6 or 21 are omitted.

I claim:

1. A metallic clip for ceiling structures having a T-shaped suspension head, a depending skirt, a flange extending at substantially a right angle from the skirt, and a second flange extending from the outer line of said rst ange across the latter and beyond the line of said skirt and forming a resilient seat below said rst flange.

2. In a ceiling structure, the combination of a metallic clip having a T-shaped suspension head,

the skirt and forms a wide cross-saddle for the a depending skirt and opposite ylateral flanges l and beyond the line of said skirt and forming a resilient seat below said iirst ilsnge. p v

4. In s. ceiling structure, the combination of s 2,893,971 x I l metallic clip bovins e 'r-shsped head, s depending skirt and opposite lateral iisnzes forming a resilient seat, 'T-shaped tile-suspending members whose iianges interlock with said seat and form supports for ,an acoustical tile, and T-shaped cross-suspending members whose flanges are cutback in line with the flanges of the T-members and whose. vertical portions rest on said T- members.
